Shreveport police are looking for a couple of thieves...and they need your help. They say the evening of December 6th, two black males with slim builds -- one wearing black material over his face and one wearing white material over his, walked up to an ATM customer in the 4600 block of Hilry Huckaby. The man in the black mask told the woman he had a weapon, and demanded money. The two suspects got money and took off on foot. Investigators believe one or both men may be responsible for robbing another customer at the same ATM on December 1st. Take a look at the video posted below. If you recognize either man in it, contact Shreveport-Caddo Crime Stoppers -- which is offering a $500 reward for information leading to the men's arrests.
